[GCC 9.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.

import pylandau
Traceback (most recent call last):
File "", line 1, in
File "pyLandau/cpp/pylandau.pyx", line 1, in init pylandau

Thanks for reporting this and sorry for the late reply. I observed similar issues that should be resolved with the latest release.

What numpy version are you using? Can you try to install it within a virtual environment created from scratch?

I keep getting the same error. Could it be possible to upgrade the package so it's compatible with numpy-1.26.2?

@IrisP25 The current version works well for me with numpy 1.26.2 (see environment below). Can you provide me with more information about your python environment? And try the package in a fresh environment as well?

Python 3.10.12
